Claims. (01. 122-39) This invention relates to boilers for hot water or steam systems, one of the objects being to provide a simple, compact and efiicient means whereby water in the boiler will be presented in a long and broad thin sheet to the heating means so that the temperature will be raised quickly.

A further object is to form flatwatercondum tors of zig-zag shape which form, between them, a succession of restrictions or throats and expansion chambers so that they serve as baffles to insure intimate contact of hot gases and other products of combustion with the surfaces of the conductors. I A still further object is to provide a boiler which can be cleaned readily and the parts of which can be quickly assembled or taken apart for making repairs or replacements.

A still further object is to provide a boiler which is substantially instantaneous in action and can be operated at low cost.

A still further object is to provide a boiler of high efiiciency which can be manufactured at lower cost than other boilers for similar purposes inasmuch as coils and tubes are eliminated.

Another object is to provide a boiler which gives maximum efiiciency in proportion to its size, it being possible to employ the same not only for heating homes and larger buildings but also for heating vehicles and for generating steam to be used in the operation of motor vehicles.

Another object is to provide a boiler which can utilize any kind of fuel such as woodycoal, oil, etc.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is a vertical transverse section through the casing of the boiler, the conducting units being shown in elevation and a portion broken away.

Figure 2 is a similar view taken at right angles toFigure 1.

Figure 3 is an enlarged vertical section through one of the couplings.

Referring to the figures by characters of reference, I designates the casing of the boiler which, in the present structure, i erected on a base 2 in which the heating meanscan be located. This heating means can be in the nature of a fire-box for burning any kind of a fuel. Casing I is rectangular in cross-section and is provided at each side with a. door 2' so that access can be had readily to the interior thereof for the purpose of cleaning. The rectangular top 3 is adapted to open into a stack as indicated at 4 and can be removably mounted on the casing.

The boiler is provided with a water container in the form of opposed connected hollow members 5 which are fiat and substantially rectangular, these members being extended close to the walls of the casing but spaced therefrom and the members of each group being arranged in zig-zag formation. Each member is provided at the central portion of its upper and lower'edges with an elongated neck 6 and the necks of the different members are connected together by bolts I or the like. The members 5 are oppositely arranged, as before stated and thus they cooperate to form between them superposed throats 8 opening into expansion spaces 9. The opposed series of members 5 are coupled together at the top by bolting together the necks at the top thereof. All of the members'are of thesame size and configuration and, consequently, any number of them can be coupled together to form a boiler of any size desired. The lower members of the opposed series diverge downwardly and to the neck of one of them is connected a feed pipe I0 whereby water can be supplied to the boiler as needed. This feed pipe hasthe usual valve I I and can also be provided with a branch I2 extending to a supplemental coiled tube I3 leading to an outlet I I. This coil is not in communication with the members 5 but is merely a supplemental water heating means which can be used for domestic purposes. I

A pressure gauge I5 is connected to the upper portion of one of the upper members 5 and an outlet pipe I6 is extended from the lower portion of the lower member 5 opposite to the one to which the pipe I0 is extended. A water gauge H can be connected to an intermediate member 5 is shown at I8.

Wherever desired drain plugs I9 can be located in the members 5.

In practice water to be heated or converted into steam is directed into the lower member 5 of one of the series from the pipe I0 and rises within the members successively on that side and then travels downwardly within the members of the other series until it reaches the pipe I6 which is the outlet. Heat generatedbelow the members will cause the temperature of said members to be raised quickly because of their broad surfaces and if solid or oil fuel is being used, the hot products of combustion flowing toward the outlet 4 will pass successively through the throats 8 and expansion chambers 9, quickly and thoroughly heating the members and rapidly raising the temperature of the water so as to convert it either into hot water or steam which can be employed for any purposes desired.

It will be noted that all of the members 5 are of the same construction as has heretofore been pointed out so that it thus becomes possible to readily assemble a boiler of any size needed; Furthermore any one of the members can be easily removed for the purpose'of making repairs or replacements, all that is necessary being to uncouple it from the next adjoining member and withdraw it through the adjacent door opening. By providing the several doors the interior of the boiler can be cleaned easily as can also thesurfaces of the members 5.

What is claimed is: v

1. In a boiler the combination with a casing, of, opposed series of flat water-conducting members, the members of each series being coupled together and. arranged in zig-zag relation, the upper. members of the two series being coupled together, means for supplying water to the lower member of one series, an outlet extending from thelower member of the other series, and all of the members cooperating to provide a passage for, products of combustion comprising. restrictions or throats and expansion. chambers alternatelyarranged.

2. A boiler including a combustion chamber, a casing erected thereon having an outlet at its top, opposed series of flat water conducting members within the casing, the members of each series being coupled together to permit flow of water from one member to the other and the members of opposed series being coupled together at the top to permit flow of water therebetween, the members of the opposed series being disposed in zig-zag relation to provide between said series expansionv chambers and throats connecting the chambers, the lower members of the two series diverging downwardly toward the combustion chamber, and means for feeding water to one endof one of the series, there being an outlet in one of the members of the other'series.

3, In a boiler the combination with a combustion chamber, of a casing. erected thereon, op-

posed series of water conducting members in the casing, all of the members being flat and substantially rectangular, the members of each series being detachably coupled and in communication with each other, the upper members of the two series being coupled together and in communication with each other, the members of each series also being arranged in zig-zag formation whereby the members of the opposed series cooperate to provide expansion chambers and throats opening into the chambers, the lower members of the opposed series diverging downwardly toward the combustion chamber.

4. In a boiler the combination with a combustion chamber, of a casing erected thereon, opposed series of water conducting members in the casing, all of the members being fiat and substantially rectangular, the members of each series being detachably coupled and in communications with each other, the upper members of, the two series being coupled together and in communication with each other, the members of each series also being arranged in zig-zag formation whereby the members of the opposed series cooperate to provide expansion chambers and throats opening into the chambers, the lower members of the opposed series diverging downwardly toward the combustion chamber, there being an outlet at the top of the casing for products of combustion, means for directing water into one end of one of the series of members, and an outlet element extending from the corresponding end of the otherseries of members.

5. In a boiler the combination with a combustion chamber and a casing erected thereon having a top outlet for products of combustion and doors in its walls, of opposed series of. fiat waterconducting members, the members of each series being in Zig-zag relation, means for detachably coupling together the members of each series, means for detachably coupling together the upper members of the two series, all of the members and their couplings cooperating to provide a continuous water conductor extending from the lower end of one series to thelower end of the other series, the opposedseries of members cooperating to provide between, them expansion chambers and throats connecting saidchambers, means for feeding water to the lower end of one of the series, and an outlet element extending from the lower end of the other series. 1
